Launch4j for jar to exe
Launch4j for jar to exe
似乎无法弄清楚为什么当我 运行 我的 .exe 文件由 launch4j 创建时，我的 JFileChooser 从未出现。许多人主要讨论此错误的 class 路径，但我没有意识到解决方案。
错误 1：
no main manifest attribute in C:\Users\Documents\...\HPLCData.exe
现在，如果我将 class 路径更改为 KFile.Main，则会收到此错误消息
错误 2：
Error: Could not find or locate main class KFile.Main
错误 3：
错误：找不到或找不到主要内容 class KFile.class
诚然，我是 java 的新手，也许答案就在眼前，或者很明显，如果是的话，我很抱歉。否则，我读到的东西指向 class 路径的问题，我不完全确定我需要更改什么。
我有点想知道它是否与生成的 xml 文件中的部分有关，但我不知道那里会发生什么。我试过改变各种奇怪的东西， closest post I found had mentioned something about using the full class path. Or maaybe there is a problem with the jar wrapping, but I don't think so as I double checked this
这里是 launch4j 生成的 .xml 文件，用于包装 .exe 文件。

如消息中所示，Launch4J 似乎调用配置中指定为 mainClass 的任何 class 的 Main 方法。所以：
对于 KFile.class，您需要在 package KFile 中有一个名为 class 的 class。这甚至是不可能的，因为你不能有一个名为 class 的 class；是保留字
对于 KFile.Main 你需要在 package KFile.
Main 的 class
您没有包裹声明，您的 class KFile 在默认包裹中。所以你需要的声明是
<mainClass>KFile</mainClass>
